Ambien is classified as a hypnotic.. There is problems with sleep eating or driving , having sex etc and not be aware. until they wake up and realize they baked 10 cakes overnight ( yes I did this years ago) for some people.

They typically start to lose effectivness for most people over time.

Its worth a shot ,but as previously advised ,, make sure you take it and stay in bed , also good idea take it on a night that you dont have to get up and function so you can determine how it effects you .

Good luck
